Paint blisters or bubbles occur when the paint film lifts from the underlying surface. The loss of adhesion between the paint film and surface is usually caused by heat, moisture or a combination of both.
What Makes Paint Bubble?
When paint bubbles, it‘s usually because of one of three things: incorrect surface preparation, poor quality paint, or extreme temperature changes. Let‘s take a closer look at each of these potential causes.
Incorrect surface preparation is the most common cause of paint bubbling. If the surface you‘re painting isn‘t clean, smooth, and dry, the paint will have a hard time adhering to it.
This can cause the paint to bubble and peel. Poor quality paint is another common cause of paint bubbling. If you use paint that‘s old or of poor quality, it‘s more likely to bubble.
This is because low–quality paint is thinner and less durable than high–quality paint. Extreme temperature changes can also cause paint to bubble.
If the temperature is too hot or too cold, the paint will expand and contract, which can cause it to bubble. If you‘re having trouble with paint bubbling, the best thing to do is to consult a professional painter.
They‘ll be able to diagnose the problem and recommend a solution.
